Problems solved by technology

However, these representations have their own limitations in theory and practical application:
However, the nodes and slots in the framework are all based on symbolic expressions, which do not have certain semantics
In addition, because there is no fixed reasoning mechanism, it is less operable
[0008] In terms of domain knowledge system construction, due to differences in knowledge representation, organizational structure, and classification criteria, knowledge systems in different domains cannot achieve the purpose of knowledge sharing and mutual service, resulting in a waste of information and knowledge resources

Embodiment Construction

[0017] In the following, in conjunction with the accompanying drawings, how to construct the knowledge banyan network expression system, construct the knowledge reasoning and service framework of the knowledge banyan network, build the field banyan knowledge system and use the knowledge reasoning and service framework of the knowledge banyan network to perform information retrieval systematically.

[0018] The knowledge banyan tree network expression system and service framework diagram of the present invention are as follows figure 1 shown. On the basis of constructing the knowledge expression system of the knowledge banyan network, the invention constructs a domain banyan knowledge system by designing a knowledge reasoning and service framework based on the knowledge banyan net, and provides data, information, and knowledge management, reasoning, and retrieval services for the domain.

[0019] The function and design of each process are described in detail below.

[0020] S...

Abstract

The invention discloses a novel method for domain knowledge representation and service, namely, a knowledge banyan net representation system and a service framework. The knowledge banyan net representation system can represent declarative knowledge and procedural knowledge simultaneously, the declarative knowledge described by using the knowledge banyan net representation system contains attribute description knowledge and relevance knowledge, and the procedural knowledge refers to inferential rules and methods on the basis of the declarative knowledge described by using the knowledge banyan net representation system. A domain system and a knowledge service platform can be quickly established for providing management and retrieval of data, information and knowledge for a domain by using the knowledge banyan net representation system and the service framework. A knowledge representation system has the characteristics of little domain restriction and various representation forms, further supports sharing among different domain knowledge, and provides a flexible and intelligent method of knowledge representation and resource management and retrieval for vertical domain searching.

Description

technical field [0001] The invention belongs to the field of computer artificial intelligence and relates to application technologies such as knowledge representation, natural language processing, and semantic information processing, and proposes a new domain knowledge expression and knowledge service method for knowledge representation, knowledge reasoning, and domain knowledge services. Background technique [0002] Knowledge representation is the process of describing and formalizing human knowledge with symbols and methods that computers can accept and process. Knowledge representation has always been the hotspot and core of artificial intelligence research. The research includes knowledge expression forms, various knowledge representation methods, measurement calculations, etc. [0003] A good knowledge representation method must first conform to the knowledge storage structure of the human brain, secondly, it should have a good representation form and a complete struct...
